Thanks for the answer. I learned that the backend is implemented in Clojure, so presumably de-serializing JSON means client-side queries trivially become Clojure data usable for databases like Datomic, Datascript, etc.

I noticed Postgres is used as the storage layer for Instant's triple store. I'm still curious why making a custom triple store over using e.g. XTDB v1. Like Instant's data store, XTDB is schemaless, and it features a Datalog engine capable of basic query planning. For instance, the order of where clauses doesn't negatively impact performance, unlike Datomic. What were the show stoppers in adopting solution like XTDB?
